AXM-120 VR conditioner

The AXM-120 VR Conditioner is designed to convert analog sine wave signals from VR (variable reluctor) sensors into clean 0–5V square wave signals suitable for modern ECUs. It’s the perfect solution when your ECU doesn’t have enough onboard VR inputs or you need to stabilize noisy cam/crank signals. This module is ideal for camshaft, crankshaft, and wheel speed sensors and supports a wide variety of signal types and configurations. Common Applications MS3Pro Gen 1 / MS3X: Add extra VR inputs when onboard conditioners are limited Four-wheel traction control: Enables reading all four wheel speed sensors Noisy VR cam sensors: Great for problematic 24/1 Nippondenso or Subaru 6/7 triggers Any VR signal conversion: Converts to square wave for easier ECU processing Key Features Signal Conversion: Converts sine wave VR sensor signals to a square wave 0–5V output Built-in Noise Rejection: Adaptive filtering only accepts valid high-energy pulses High Compatibility: Works with a wide range of cam/crank and speed sensors Motorsport-Ready Design: Uses an Amphenol AT connector (Deutsch DT compatible) Conformal coated PCB for moisture protection (do not submerge) Connector and pins included Technical Specifications Input: A/C sine wave from VR sensor Minimum trigger voltage: 45 mV Max input voltage: 108V peak-to-peak Output: 0–5V DC square wave (no pull-up required) Output pulse: Triggered on falling edge (input going negative) Supply Voltage: 7.0 to 22.0 volts DC Current Draw: < 20 mA
